SULPHURIC ACID PLANTS
Sulphur’s annual survey of recent and planned construction projects in the sulphuric acid industry includes several large-scale acid plants both for phosphate processing and to capture sulphur dioxide from smelters.
VK Arora of KPI examines the technical and operational challenges of decarbonising legacy and new ammonia plants, drawing on a European case study of full-scale conversion supported by robust process and integration design. It also presents three US case studies exploring partial strategies, such as green hydrogen blending and oxygen enrichment, to reduce CO2 emissions and improve throughput. Together, these examples highlight a phased, cost-effective approach to decarbonisation, with blue hydrogen serving as a near-term transitional feedstock.
Casale is specialised in revamping natural gas-based methanol plants. Decarbonisation of methanol plants is a goal for many producers achievable with a proper revamping strategy. Pietro Moreo of Casale discusses how Casale’s innovative technologies and extensive experience ensure reliable efficient capacity and performance enhancements together with CO2 emissions reduction tailored to meet revamping project targets.
By combining oxygen-blown Lurgi™ autothermal reforming (ATR) technology with Cryocap™ H2 carbon capture technology, Air Liquide offers an innovative plant configuration to meet the need for a central production facility offering flexible product diversification with hydrogen and ammonia at a scale that satisfies extensive decarbonisation targets.
Granulation offers a scalable and reliable way of recovering crop nutrients from waste, says Nick Reckinger of FEECO International.
